The Service Kit 40-50HP Super is a complete OEM maintenance solution specifically designed for Mercury 40HP and 50HP 2-Stroke Super outboard engines. Built to meet Mercury’s exact factory specifications, this comprehensive kit provides all the essential components required to perform a full routine service and keep your engine running reliably and efficiently across all conditions.

Routine maintenance is crucial for extending engine life, preserving fuel efficiency, and avoiding costly breakdowns. The Service Kit 40-50HP Super simplifies the process by combining all required parts into one convenient, easy-to-use package. Included in the kit are a water pump impeller and housing, fuel filter, spark plugs, drain plug gaskets, and a complete set of seals and o-rings—each engineered to deliver precise fit and lasting durability in harsh marine environments.

The water pump impeller is a key component in your engine’s cooling system, responsible for circulating water to regulate engine temperature. Replacing the impeller at recommended service intervals helps prevent overheating and safeguards internal components from thermal stress and damage.

The included fuel filter helps maintain clean fuel delivery by capturing debris and contaminants before they reach critical engine components. A clean fuel system supports better combustion, smoother operation, and improved throttle response. The spark plugs deliver consistent ignition, reliable cold starts, and optimal performance across all RPM ranges.

All included seals and gaskets are marine-grade, designed to resist corrosion, pressure, and vibration. They help maintain a leak-free seal between components, protecting the engine’s internal systems from moisture intrusion and wear. The use of genuine OEM parts ensures compatibility, performance, and continued warranty compliance.

Whether you’re a seasoned marine technician or a hands-on boat owner, the Service Kit 40-50HP Super offers a reliable, all-in-one solution for regular maintenance. This kit saves time by eliminating the need to source individual parts, and it ensures that no critical component is overlooked during servicing.
